Unofficial results from the Oglala Sioux tribal election show President Theresa Two Bulls trailing former president John Yellowbird Steele.

KEVN-TV reports that with challenge ballots still to be dealt with, Steele has a 76-vote lead.

Challenge ballots are those cast by someone whose name is not on the list at the polls. That persons voting eligibility is determined later.

Unofficial results show Kevin Keckler as leading in the Cheyenne River Sioux tribes chairman election. KGFX radio reports that Keckler has a 100-vote lead over Derek Bartlett. Candidates have until Friday afternoon to protest any of the 225 challenge ballots.
